as per a normal car. Fluid nut is located on side of oil tank. Ensure oil is warm and not driving temperature. Unscrew nut and pour oil into vessel and replace with new oil but putting back on fluid nut and pouring in through the oil slot on top of oil tank
Tank car
because oil is refined into gas
yes
it can damage your car. your gas tank is just a tank with gas, it's kind of hard to damage it.
You can go to a place like Jiffy Lube to get your oil changed. Or you can do it yourself. To do it yourself, first warm up the car to make the oil warm. Then take out the plug and filter. Drain the oil. Fill it up with new oil. And lastly, screw the cap back on.
drain tank and refill
No, but it helps. Warm oil flows out much more easily.
The question is how did oil get in the fuel tank? If there was very little oil put in the tank as in less than a couple of quarts then just fill the tank full and drive the car. The oil will be burned with the fuel and will do no harm. If there was more than a couple of quarts, you can siphon it out with a hand pump. You can get enough out to then fill the tank and drive the rest out.
It won't run properly, you'll have to drain the oil all out.
No. There is a oil tank much like your car that you top off.
Go under the car and it is on the passager side just in front of the oil tank.
